Frame/Fork fatigue

My work recently introduced a cycle to work scheme capped at £1111.11. You were tied into one supplier but had a good choice of quality bikes.

I choose a Cannondale CAAD8/105. This is inferior to my Cube Agree HPA/Ultegra on paper. However it rides much better than my Cube especially with out the saddle efforts. I feel the all carbon fork on the Cube may be absorbing energy instead of transmitting it.

Thoughts?

    What's the question?

    Is my fork absorbing energy rather than transmiting it?

    Not that I can see how you transmit energy through a fork... It may stop the hum of the road but thats about it.

    If one bike feels more sluggish out of the saddle, I'd be more inclined to look at the wheels/tyres.

    The Cube is currently running Fulcrum 5's with Conti Ultra Sports. CAAD has "Maddux Speed 3.0" wheels and Swalbe Lugano tyres. I understood these wheels were quite poor. :?

    I have set the bike as close as I can in terms of position. There is one difference that may have an effect? The bars on the cube have a small angle at the stem so the bars sweep back slightly.

    Maybe its the new bike feeling? Going to try it today with the race wheels in.

    What possible 'energy' could be absorbed by the fork? Alternatively, what possible 'energy' could a fork transmit - and how?

    Two bikes might feel different - that's not unreasonable - but the main factor behind a carbon v alu steerer is weight saving.

    imposter, that was exactly my point.

    ps, in engineering/physics everything that moves has or contains energy. A humming fork contains energy and the carbon absorbs that in the same way a shock absorber absorbes energy.

    My Fulcrum 6s are shockingly poor at out of the saddle efforts.

    On my Specialized Tarmac I've had to remove the wheel magnet as the wheel buckles so much when you stand up and sprint that the magnet hits the Garmin sensor. When I'd sit down after the sprint the wheel would straighten after a few seconds and the hitting would stop.
